ADUM2210SRWZ Overview
A digital isolator is a semiconductor device that transmits data or power across an electrical isolation barrier while blocking high voltages, ground loops, and noise. Digital isolators sit hierarchically above optocouplers in the signal isolation category, providing faster data rates, lower power consumption, and tighter channel-to-channel timing. As members of the iCoupler family, ADUM2210 devices use on-chip transformers to magnetically couple data across the isolation barrier, replacing legacy LED-and-photodiode optocouplers in most new designs.
Key features include a typical propagation delay of 20 ns, channel-to-channel matching of 1 ns, low dynamic power consumption of 1.6 mA per channel at 1 Mbps, and IEC 61000-4-x enhanced system-level ESD performance. The wide-body SOIC-16 package provides the reinforced 5 kVrms isolation and is rated for industrial temperature ranges of -40C to +125C. Two speed options (1 Mbps grade ADuM2210 / 25 Mbps grade ADuM2211) let designers balance speed and EMI.
The ADUM2210SRWZ utilizes ADI's proprietary transformer-on-CMOS process, integrating the isolation barrier, refresh circuitry, and encoder/decoder logic on a single monolithic die. Each channel contains a differential transformer winding driven by edge-detection circuitry, providing DC-correctness without continuous carrier signal and yielding low EMI. Default channel configuration is two channels in the same direction (see ADUM2211 for opposite-direction option).
Typical applications include industrial field bus (RS-485, RS-232, CAN) isolation, motor drive gate driver signal isolation, microcontroller UART/SPI isolation, isolated power supply feedback, and medical equipment patient-isolation interfaces. The 5 kVrms rating suits 230 V mains and reinforced IEC 60950 / IEC 62368-1 system-level designs.
When designing with this device, observe the layout rules of VCC1 and VCC2 bypass capacitors (0.1 uF ceramic placed within 2 mm of each supply pin). The device requires no external drivers or clock; place input signals through series resistors when driving long PCB traces to limit inrush current into the transformer windings.

Typical Applications
ADUM2210SRWZ is suitable for 7 applications: Industrial RS-485 Bus Isolation, Motor Drive Gate Driver Signal Isolation, Microcontroller UART / SPI Isolation, Isolated Power Supply Feedback, Medical Equipment Patient Isolation, CAN Bus Node Isolation, Industrial PLC I/O Isolation.
Industrial RS-485 Bus Isolation
The ADUM2210SRWZ is well-suited for isolating RS-485 transceiver signals in industrial field bus networks. Its 5000 Vrms isolation rating blocks ground potential differences between PLCs, motor drives, and field sensors spaced far apart on a factory floor, while its 25 kV/us CMTI rejects common-mode transients from VFDs and switch-mode power stages. The 1 Mbps data rate comfortably covers RS-485 half-duplex traffic at 10 Mbps maximum when paired with modern transceivers; for high-speed networks, drop-in the pin-compatible ADUM2211SRWZ (25 Mbps). At 1.6 mA per channel at 1 Mbps, the ADUM2210SRWZ adds minimal supply overhead to the isolated bus node. Recommend placing 0.1 uF ceramic bypass caps within 2 mm of pins 1 and 8.
Recommended
Motor Drive Gate Driver Signal Isolation
In IGBT or MOSFET gate driver stages, the ADUM2210SRWZ transmits PWM control signals across the high-voltage isolation barrier between the low-voltage MCU and the high-side gate driver. Its 25 kV/us CMTI is critical here: motor drive switching nodes routinely produce dv/dt above 10 kV/us, and lower-CMTI isolators can produce false trigger pulses that shoot through the bridge. The 5000 Vrms withstand voltage covers the reinforced insulation requirements of 230 V and 480 V AC mains-referenced motor drives. 20 ns propagation delay preserves PWM timing accuracy at moderate switching frequencies; for higher-frequency GaN drives, upgrade to ADUM2211SRWZ (25 Mbps, same footprint).
Recommended
Microcontroller UART / SPI Isolation
The ADUM2210SRWZ isolates low-voltage microcontroller UART, SPI, or general-purpose logic signals in mixed-voltage systems where a 3.3 V MCU must talk to a 5 V peripheral across a galvanic barrier. Both sides accept 3.0 V to 5.5 V supplies independently, allowing level translation and isolation in a single SOIC-16 wide-body device. Channel-to-channel matching of 1 ns makes it usable for synchronous serial interfaces up to its 1 Mbps limit. Compared to optocouplers, the iCoupler architecture avoids LED aging and CTR degradation, providing stable timing over the -40C to +125C operating range.
Recommended
Isolated Power Supply Feedback
The ADUM2210SRWZ provides isolation for the primary-to-secondary feedback path in isolated DC-DC converters, replacing an optocoupler plus TL431 combination with a single magnetic-coupling isolator. Its 5 kVrms withstand meets reinforced insulation requirements for industrial and medical supplies up to 230 VAC mains referenced. Lower propagation delay (20 ns vs 1-2 us optocoupler) enables higher-bandwidth control loops and faster transient response in the regulated output. Note that for high-voltage AC-DC designs a separate isolated bias supply is required; pair the ADUM2210SRWZ with an ADI isoPower device such as ADuM5020 if integrated isolated power is needed.
Recommended
Medical Equipment Patient Isolation
The ADUM2210SRWZ provides 5000 Vrms reinforced isolation suitable for patient-connected medical equipment such as patient monitors, infusion pumps, and ECG systems that require isolation per IEC 60601-1. Its enhanced system-level ESD performance per IEC 61000-4-x helps the system survive electrostatic discharge events during clinical use. The low 1.6 mA per channel power consumption suits battery-powered portable devices, and the wide-body SOIC-16 package provides the clearance and creepage distances required by medical safety standards. Two-channel configuration handles bidirectional UART or one control plus one status signal.
Recommended
CAN Bus Node Isolation
The ADUM2210SRWZ is well-matched for isolating Controller Area Network (CAN) bus nodes in automotive and industrial control systems. While CAN bus data rates up to 1 Mbps are within the device's rated 1 Mbps, the 5000 Vrms isolation provides reinforced insulation between the bus and the microcontroller, preventing ground loops across long harness runs. Pairing with a CAN transceiver like ADM3053 (which has integrated isolation) can simplify the BOM, but for retrofit designs or where the transceiver must remain on the bus side, the ADUM2210SRWZ is a reliable two-channel solution with strong 25 kV/us CMTI.
Recommended
Industrial PLC I/O Isolation
Programmable Logic Controllers (PLCs) require signal isolation between field wiring and the central processor to protect against voltage transients, ground loops, and ESD events. The ADUM2210SRWZ serves as a 2-channel isolator for digital inputs or outputs on PLC I/O modules, with 5 kVrms withstand suitable for 230 VAC industrial mains. Its wide-body SOIC-16 package provides the clearance/creepage required by IEC 61131-2 industrial control standards, while its 1.6 mA per channel consumption keeps thermal loading in dense I/O cards to a minimum.

Design Notes
Place 0.1 uF low-ESR ceramic bypass capacitors on both VDD1 (pin 1) and VDD2 (pin 10) within 2 mm of the device pins. The iCoupler architecture draws 1.6 mA per channel at 1 Mbps and surges briefly during edge transitions; inadequate bypassing can cause VDD sag and propagation delay jitter. Bulk 1 uF to 10 uF capacitors on each supply rail are recommended for industrial motor-drive environments.
Maintain at least 8 mm clearance and creepage between side-1 and side-2 copper pours to preserve the 5 kVrms isolation rating in the SOIC-16 wide-body package. Remove soldermask and copper from the area beneath the device body if possible; the ADI evaluation board layout removes copper entirely under the package to maximize the isolation distance. Do not run any traces or vias under the device body.
Do not load VOA/VOB outputs beyond their rated drive capability or place large capacitive loads (>50 pF) directly on the output pins - this slows edges and degrades CMTI margin. If driving long PCB traces or cables, add a 100-ohm series resistor close to the output pin to dampen reflections. Do not exceed 5.5 V on either VDD supply or polarity reversal will damage the device.
Estimated: ground-plane return path inductance on each side should be minimized by stitching vias around the supply and ground pins. The two ground pins (GND1, GND2) must connect to their respective side grounds; do not bridge them, as that defeats the isolation. For 4-layer boards, place a continuous ground plane on layer 2 directly under the device to control return-current paths.
Channel-to-channel matching is specified at 1 ns maximum, which is suitable for synchronous serial interfaces up to the 1 Mbps limit. For applications that require matched timing in both directions (e.g., full-duplex SPI), use the ADUM2211SRWZ which has the same package and pinout but supports 25 Mbps for higher data rates. Place source-series termination when driving cables or backplanes to limit reflections and reduce radiated EMI.
